fuel leak above tank

2013 Tundra w/ 175000 miles. noticed fuel smell and now can see fuel leaking from a cylindrical part above the tank with wires going into it and kind of over the frame. This is near the front of the tank near the front tank strap. Kind of between the frame and the tank. What is this? I'm sure I need to drop the tank to replace it but did a search and can't find what it is.
Thanks Also right against the emergency brake line.

Edit: I am posting a picture and you can see it is above the frame. The fuel is coming out of the little hole. You can see it is wet below the hole. It only leaks when there is fuel pressure, also the truck is starting a little bit harder since the leak

 

I figured it out. You can't find much on it or even get the part aftermarket because it is only on E85 trucks. It has to do with fuel pressure when burning corn gas, which I have never done. Had to lower the tank by unhooking fuel lines and filler hose. Whole project probably 4 hours. Running great again.

Glad you got it figured out and fixed. Sounds like a real pain in the ass to get to.

welcome to the forum! Post some more pictures of your truck!

 

These FFV E85 trucks sound like a pain in the ass.
